Distinctive Scapular Dyskinesis with Hypertrophy of the Serratus Anterior Muscle on Computed Tomography: A Case Report

초록

A 27-year-old man presented with a 5-year history of left periscapular muscle spasm and constant shoulder pain in activities of daily living. Magnetic resonance imaging (MRI) and physical examination revealed scapular dyskinesis without pathologic lesions in the rotator cuff tendon and labrum. However, there was hypertrophy of the serratus anterior muscle on computed tomography (CT). Scapular dyskinesis can be caused by isolated hypertrophy of the serratus anterior. After 4 months of physiotherapy, including manual therapy, therapeutic exercises, and neuromuscular retraining, the patient recovered normal scapular movement and reported no pain.
